RESUMEN
ABSTRACT Purpose: A systematic review of the literature with available published literature to compare ileal conduit (IC) and cutaneous ureterostomy (CU) urinary diversions (UD) in terms of perioperative, functional, and oncological outcomes of high-risk elderly patients treated with radical cystectomy (RC). Protocol Registration: PROSPERO ID CRD42020168851. Materials and Methods: A systematic review, according to the PRISMA Statement, was performed. Search through the Medline, Embase, Scopus, Scielo, Lilacs, and Cochrane Database until July 2020. Results: The literature search yielded 2,883 citations and were selected eight studies, including 1096 patients. A total of 707 patients underwent IC and 389 CU. Surgical procedures and outcomes, complications, mortality, and quality of life were analyzed. Conclusions: CU seems to be a safe alternative for the elderly and more frail patients. It is associated with faster surgery, less blood loss, lower transfusion rates, a lower necessity of intensive care, and shorter hospital stay. According to most studies, complications are less frequent after CU, even though mortality rates are similar. Studies with long-term follow up are awaited.

ABSTRACT Objective: To characterize the contribution of the extirpative and reconstructive portions of radical cystectomy (RC) to complications rates, and assess differences between urinary diversion (UD) types. Materials and Methods: We conducted a retrospective cohort study comparing patients undergoing UD alone or RC+UD for bladder cancer from 2006 to 2017 using ACS National Surgical Quality Improvement Program database. The primary outcome was major complications, while secondary outcomes included minor complications and prolonged length of stay. Propensity score matching (PSM) was utilized to assess the association between surgical procedure (UD alone or RC+UD) and outcomes, stratified by diversion type. Lastly, we examined differences in complication rates between ileal conduit (IC) vs. continent UD (CUD). Results: When comparing RC + IC and IC alone, PSM yielded 424 pairs. IC alone had a lower risk of any complication (HR 0.63, 95% CI 0.52-0.75), venous thromboembolism (HR 0.45, 95% CI 0.22-0.91) and bleeding needing transfusion (HR 0.41, 95% CI 0.32-0.52). This trend was also noted when comparing RC + CUD to CUD alone. CUD had higher risk of complications than IC, both with (56.6% vs 52.3%, p = 0.031) and without RC (47.8% vs 35.1%, p=0.062), and a higher risk of infectious complications, both with (30.5% vs 22.7%, p<0.001) and without RC (34.0% vs 22.0%, p=0.032). Conclusions: RC+UD, as compared to UD alone, is associated with an increased risk of major complications, including bleeding needing transfusion and venous thromboembolism. Additionally, CUD had a higher risk of post-operative complication than IC.

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

ABSTRACT Introduction: Acute kidney injury (AKI) after major surgeries is associated with significant morbidity and mortality. We aim to report incidence, predictors and associated comorbidities of AKI after radical cystectomy in a large cohort of patients. Materials and Methods: We conducted a retrospective analysis of 1000 patients who underwent open radical cystectomy in a tertiary referral center. Perioperative serum creatinine measurements were used to define AKI according to the RIFLE criteria (as Risk, Injury and Failure). The predictors of AKI after surgery were determined using univariate and multivariate analyses. Results: Out of 988 evaluable patients, AKI developed in 46 (4.7%). According to RIFLE criteria; AKI-Risk, AKI-Injury and AKI-Failure occurred in 26 (2.6%), 9 (0.9%) and 11 (1.1%) patients, respectively. Multivariate analysis showed that performing nephroureterectomy with cystectomy (Odds ratio [OR]: 4.3; 95% Confidence interval [CI]: 1.3-13.6; p=0.01) and the development of high grade complications (OR: 3.8; 95% CI 1.9-7.2; p<0.0001) were independently associated with AKI. Conclusions: AKI is a significant morbidity after radical cystectomy and the term should be included during routine cystectomy morbidity assessment.

ABSTRACT Objective: To present our technique of ureteroileal bypass to treat uretero-enteric stric- tures in urinary diversion. Materials and Methods: One hundred and forty-one medical records were reviewed from patients submitted to radical cystectomy to treat muscle-invasive bladder cancer between 2013 and 2015. Twelve (8.5%) patients developed uretero-enteric anastomotic stricture during follow-up. Five patients were treated with endoscopic dilatation and double J placement. Four were treated surgically with standard terminal-lateral im- plantation. Three patients with uretero-enteric anastomotic stricture were treated at our institution by "ureteroileal bypass", one of them was treated with robotic surgery. Results: All patients had the diagnosis of uretero-enteric anastomotic stricture via computerized tomography and DTPA renal scan. Time between cystectomy and diag- nosis of uretero-enteric anastomotic stricture varied from five months to three years. Mean operative time was 120±17.9 minutes (98 to 142 min) and hospital stay was 3.3±0.62 days (3 to 4 days). Mean follow-up was 24±39.5 months (6 to 72 months). During follow-up, all patients were asymptomatic and presented improvement in ure-terohydronephrosis. Serum creatinine of all patients had been stable. Conclusions: Latero-lateral ureter re-implantation is feasible by open or even robotic surgery with positive results, reasonable operation time, and without complications.

PURPOSE: To analyze the complications after robot-assisted radical cystectomy (RARC) by use of a standardized reporting methodology by a single surgeon. MATERIALS AND METHODS: We prospectively reviewed a maintained institutional database of 52 patients who underwent RARC to manage bladder cancer and were followed up in 3 months by a single surgeon at Korea University Medical Center from 2007 through 2014. All complications within 90 days of surgery were defined and categorized into 5 grades according to the Clavien-Dindo classification. Logistic regression analysis was used to identify predictors of complications. RESULTS: Fifty percent of patients (26 of 52) experienced a complication of any grade <90 days after surgery, and 11 patients (21.2%) experienced a major complication. Complications were grouped in systems-based categories. Fifty complications occurred in 52 patients and hematologic complication (transfusion) was the most common (13 of 52). Wound dehiscence, anastomotic leakage, urinary tract obstruction, mechanical obstruction, and thromboembolism occurred as major complications. Mean estimated blood loss (EBL) was 247 mL and mean total operative time was 496 minutes. The mean number of lymph nodes harvested was 24.6, with 30.5 for extended dissection. EBL (over 300 mL), operative time, and method of urinary diversion were significant negative predictors of minor complications, whereas EBL (over 300 mL) was a significant negative predictor of major complications (p<0.05). CONCLUSIONS: The present results show that the complication rate reported by use of a standardized methodology after robotic radical cystectomy is still considerable although comparable to that of contemporary robot series. EBL, operative time, and diversion methods were predictors of complications.

PURPOSE: Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. MATERIALS AND METHODS: From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. RESULTS: Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. CONCLUSION: Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit.

PURPOSE: Radical cystectomy and urinary diversion are the standard treatment for invasive bladder cancer. We analyzed the long-term (>10 years postoperatively) functional outcomes, complications, and urodynamic findings in a single center series of patients who underwent cystectomy and a Studer ileal neobladder substitution. MATERIALS AND METHODS: A retrospective chart review of 108 Studer pouches constructed during 1990 and 2011 was performed. Data were analyzed in terms of long-term (>10 years) outcomes. Complications, incontinence, voiding difficulties, upper urinary tract changes, overall satisfaction, and urodynamic findings of the reservoir were obtained. RESULTS: We evaluated 19 out of 50 patients who had lived for over 10 years postoperatively. Another 31 patients were not traced: 7 patients died following recurrence, 15 died due to exacerbation of a comorbidity, and 9 patients were lost to follow-up. Concerning complications, 6 patients had an atrophied kidney, 5 patients had moderate hydronephrosis, 5 patients had chronic recurrence of pylelonephritis, and 2 patients had voiding difficulty because of bladder neck stricture due to clean intermittent catheterization. One patient underwent an operation due to intestinal obstruction. Seven patients had incontinence; all 7 patients showed intermittently at night and 2 patients even in waking hours. Maximum bladder capacity was 484.1+/-119.2 mL, maximum flow rate was 13.6+/-9.7 mL/sec, and post-void residual urine volume was 146.8+/-82.7 mL. CONCLUSION: Long-term outcomes with the Studer orthotopic ileal neobladder have an acceptable complication rate and good functional results. However, potential adverse outcomes such as renal deterioration, dysfunctional voiding should also be considered.

PURPOSE: To study morphologic and histochemical alterations arising at the ileocystoplasty site. METHODS: Sixteen Wistar female rats were subjected to ileocystoplasty and sacrificed after eight weeks. Material collected was divided into four groups for histological and histochemical studies: Group I (control) - isolated ileum segment removed during ileocystoplasty; Group II - ileoileal anastomosis; Group III - ileovesical anastomosis and Group IV - ileal segment from the neobladder. Histological and histochemical study assessed dysplasia, metaplasia, acute and chronic inflammation, fibrosis, atrophy, hypertrophy, total mucins, sialomucins and sulfomucins. The non-parametric Wilcoxon and Mann-Whitney tests were employed in statistical analysis. RESULTS: None of the groups presented dysplasia. Acute inflammation and atrophy occurred in Groups II, III and IV, not reaching statistical significance. Metaplasia was significant only in Group III (p=0.012). Chronic inflammation, fibrosis and hypertrophy were significant in Groups II, III and IV. There was a significant increase in total mucin content in Group IV (p=0.014) and a reduction in Group III (p=0.016). Increases in sialomucins were observed in samples for Groups III (p=0.003) and IV (p=0.002) along with reduced sulfomucins in samples from Groups III (p=0.013) and IV (p=0.008). CONCLUSION: Ileocystoplasty in female rats caused squamous metaplasia, chronic inflammatory infiltration, fibrosis, hypertrophy, increase in sialomucin content, reduction in sulfomucins, and alterations in total mucin content with statistical significance, as well acute inflammatory infiltration and muscular atrophy with less intensity.
OBJETIVO: Estudar alterações morfológicas e histoquímicas nas ileocistoplastias em ratos fêmea. MÉTODOS: 16 ratos fêmea foram submetidos à ileocistoplastia, sacrificadas após oito semanas. O material coletado foi e dividido em quatro grupos para análise morfológica e histoquímica: Grupo I (controle) biópsia intestinal no momento da cirurgia; Grupo II - anastomose íleo-ileal; Grupo III - anastomose íleo-vesical e Grupo IV - segmento intestinal da neobexiga. Os parâmetros avaliados foram: displasia, metaplasia, processo inflamatório agudo e crônico, fibrose, atrofia, hipertrofia, conteúdo total de mucinas, sialomucinas e sulfomucinas. Utilizou-se os testes não-paramétricos de Wilcoxon e Mann-Whitney para estudo estatístico. RESULTADOS: Não houve displasia. Processo inflamatório agudo e atrofia ocorreram nos grupos II, III e IV, sem significância estatística. Metaplasia com significância estatística ocorreu somente no grupo III (p=0.012). Processo inflamatório crônico, fibrose e hipertrofia foram significantes nos grupos II, III e IV. Observou-se aumento significante no conteúdo total de mucinas no grupo IV (p=0.014) e redução no grupo III (p=0.013). Aumento significante de sialomucinas foi observado nos grupos III (p=0.003) e IV (p=0.002) e redução significante das sulfomucinas nos grupos III (p=0.013) e IV (p=0.008). CONCLUSÃO: Nas ileocistoplastias em ratos fêmea observou-se metaplasia escamosa, processo inflamatório crônico, fibrose, hipertrofia, aumento do conteúdo de sialomucinas, redução das sulfomucinas e alterações no conteúdo total de mucinas com significância estatística, bem como atrofia e processo inflamatório agudo em menor intensidade.

Purpose: To review our clinical experience with urinary continent catheterizable reservoir in children under five years of age. Materials and Methods: A total of 23 patients (16 males, 7 females) with a median age of 3.64 years were evaluated. Among these, 6 (26.08 percent) had a posterior urethral valve, 9 (39.13 percent) myelomeningocele, 4 (17.39 percent) bladder exstrophy, 2 (8.69 percent) genitourinary rabdomyosarcoma, 1 (4.34 percent) had spinal tumor and 1 (4.34 percent) an ano-rectal anomaly. Results: Perioperative complications were observed in four patients consisting of one febrile urinary tract infection, one partial operative wound dehiscence, one partial stomal dehiscence and one vesico-cutaneous fistula after a secondary exstrophy repair. The overall long-term complications rate was 40.90 percent and consisted of two stomal stenoses (9.09 percent), one neobladder mucosal extrusion (4.54 percent), three neobladder calculi (13.63 percent) and persistence of urinary incontinence in three patients (13.63 percent). The overall surgical revision was 36.36 percent and final continence rate was 95.45 percent with mean follow-up of 39.95 months Conclusion: Continent urinary diversion is technically feasible even in small children, with acceptable rates of complications.

Introducción: Existen múltiples razones por las cuales se hace necesario realizar una cistectomía radical, aunque claramente la principal es indiscutidamente el cáncer vesical. El conducto ileal u operación de Bricker ha sido, tradicionalmente, la forma más utilizada de derivación urinaria supravesical. A través de múltiples publicaciones se conocen las limitaciones y complicaciones de esta cirugía, principalmente en el largo plazo. Material y métodos: El presente estudio presenta una revisión retrospectiva de los pacientes sometidos a cistectomía y reemplazo vesical, en el Hospital Militar de Santiago, entre los años 1982 y 2008. De estos reemplazos vesicales, 23 fueron operaciones de Bricker, 4 operaciones de Studer y 1 Indiana. Se detallan las complicaciones precoces y tardías ocurridas durante el tiempo de seguimiento. Resultados: En términos generales, la serie muestra que la operación de Bricker tiene una tasa de complicaciones precoces de un 26 por ciento y de complicaciones tardías de un 17,4 por ciento. Conclusión: Consideramos que la operación de Bricker constituye una adecuada alternativa de derivación urinaria, con un índice de complicaciones aceptable en el largo plazo.
Introduction: Currently, radical cystectomies are perfomed for many reasons, but bladder cancer is still considered to be the most important one. The ileal conduit or Brickers diversion is the most common supravesical urinary diversion technique. Limitations and long term complications of this surgical technique are well known. Material and Methods: In this study we present a retrospective review of patients submitted to radical cystectomy and bladder replacement at the Hospital Militar de Santiago between 1982 and 2008. Of 28 cystectomies, 23 ileal conduits, 4 Studer procedures and 1 Indiana procedure were performed. Perioperative and long term complications are described. Results: The study shows that Brickers procedure has an early complication rate of 26 percent and a late complication rate of 17.4 percent. Conclusions: This study shows that ileal conduit seems to be a good alternative of urinary diversion, with an acceptable rate of short and long term complications.

Un porcentaje considerable de pacientes que requieren cirugía vesical con intestino corresponden a mujeres en edad fértil. El embarazo y parto en este grupo de pacientes sólo ha sido reportado de forma ocasional. El objetivo del presente trabajo es describir una serie clínica de mujeres que consiguieron gestación y parto, posterior a cirugía de ampliación o derivación vesical con intestino. Revisión retrospectiva de fichas clínicas de 6 mujeres que cursaron con una gestación exitosa, posterior a cirugía de enterocistoplastía. Se consideró: diagnóstico pre operatorio, cirugía realizada, embarazo, tipo de parto y complicaciones. Desde el año 1988 a la fecha, se ha realizado cirugía vesical con intestino en 37 mujeres en edad fértil. Seis de ellas han conseguido embarazo, con siete gestaciones reportadas. Los diagnósticos pre operatorios fueron: tres cistopatías intersticiales, dos vejigas neurogénicas y una hiperactividad idiopática del Detrusor. El tipo de cirugía fue ampliación vesical con intestino detubulizado en cuatro casos y ampliación con cierre de cuello y ostomía continente en dos. Los embarazos fueron: feto único en cinco pacientes y gemelar en una. Las complicaciones más significativas fueron infección del tracto urinario y parto prematuro. El parto correspondió a cesárea en cinco mujeres y parto vaginal en una. Posterior al parto, una paciente requirió revisión de la ostomía por prolapso e incontinencia. Las mujeres en edad fértil que han requerido cirugía vesical con intestino, pueden conseguir un embarazo y parto exitoso con baja incidencia de complicaciones.

Se evaluan en el presente estudio un total de 65 pacientes a los que se le habían colocado catéteres uretrales doble "J" o pig-tail por patologías litiásicas o no. Se estudiaron sus indicaciones, control, seguimiento, sintomatología adversa, complicaciones y tratamiento. Consideramos que los catéteres doble "J" son eficaces en el posoperatorio de cirugías endourológicas, pueden ser usados como monoterapia en las litiasis obstructivas y son útiles en las uronefrosis por compresión de la vía excretora, pero que su permanencia prolongada favorece las complicaciones

El tratamiento de muchas enfermedades de la cavidad pelviana provoca la pérdida de la continencia fecal, urinaria y a veces ambas. Se presenta la experiencia obtenida en 7 enfermos a los que se les efectuó un reservorio urinario con colon derecho con la técnica de Indiana. La enfermedad que motivó su indicación fue: cáncer ginecológico recidivado, 57,1 por ciento; cistitis actínica, 28,6 por ciento; y fístula vesico rectovaginal actínica, 14,3 por ciento. Se complicaron en el postoperatorio inmediato 2 enfermos con absceso de herida y fístula temporaria del reservorio. El período de vaciado de la bolsa osciló entre 5 y 9 horas, permitiendo un tiempo de sueño satisfactorio. El volumen promedio obtenido fue de 700cc con una continencia efectiva en todos los pacientes. Fallecieron en el postoperatorio alejado, 2 enfermos por progresión de la enfermedad y 2 por causas no inherentes a su tratamiento. No se comprobaron alteraciones ni dilataciones del árbol urinario
